Understanding Sudoku
Sudoku is a logic-based number placement puzzle that originated in Japan in the 1980s. The name "Sudoku" is Japanese for "single number" - reflecting the puzzle's core rule that each number can appear only once in each row, column, and 3x3 box.
The standard Sudoku grid is 9x9, divided into nine 3x3 boxes. Your task is to fill in the cells using numbers 1-9 while following three simple rules:
- Each row must contain all numbers from 1 to 9 exactly once
- Each column must contain all numbers from 1 to 9 exactly once
- Each 3x3 box must contain all numbers from 1 to 9 exactly once
